This is the nicest F91W mod I've seen around. Well done!

[@Techsas]

Thanks!

[@Techsas]

168 module is too thick for f91w case. You can fit in Skmei 1412 module wich has backlight like 168 but I don't think there is inverted display version of it.

[@irmese06]

As an 80s kid I strongly feel that you picked the right music for this video. That should be Casio's official theme song. Cool project, too; it makes me want to understand more about how the LCDs work.

[@Techsas]

Thanks!

[@RMBMS]

Casio should really release this exact mod as a real product

[@MammothBehemoth]

I wish there could be a black pvd case for this

[@conyo985]

They'll charge a premium for it though. The fun with the F91Ws is that it's cheap and reliable and fun to mod it. Edit: Just found out that they do sell a black gold version of the F91W with a positive display and still with the resin strap. Just change the strap to metal one and your good to go!

why diamond in quotes? those are real diamonds. Diamonds are dirt cheap now

casio f91w my favorite watch❤

[@imagebboy]

Worth the wait, you did not disappoint! I can tell you're getting more careful and calculating. I was inspired by your videos and I just did a mod where I fit an A700WE module in a F91W for a better light, nato strap, and used mineral oil (lot of trial and error to get rid of the bubbles) for more water resistance... was a lot of fun!

[@Techsas]

Man thanks! I'm trying to improve the quality of the videos. Your mod sounds awesome. I have a A700WE and cannot decide what to do with it. Can I see some pictures? If I could send some to [e-mail] I'd really appreciate it. Thanks!

[@aphoenix9349]

I would like to do this mod. No one else on KZbin talking about doing this

Sooooooo relaxing!!! ❤️

[@7CharlesV]

I'm not a huge fan of the 91 in and of itself, but I love your videos and watching you work. I've said this before, too; the music is totally, absolutely, perfection. What a great production effort on your part, makes me smile to watch you work. Hey, maybe I can do this, too... Gloves... check. Tweezers...check. Tiny screwdrivers...check. Sacrificial watch...check. Patience and tactile skills...er..check back later🙄. Thank you, Techsas!

[@sayedkhalidkameli9742]

Well that's one way to invert the display instead of peeling the polorizer off the screen, but I actually prefer the f91w band instead because it doesn't strip the hair on my rist, but still petty amazing!! Keep up the good work !!

[@Techsas]

Haha.... I agree with you on this one, it's a hair puller. This mod is purely esthetics, just love the way it looks!

[@sayedkhalidkameli9742]

I agree it looks quite nice tho , for putting it on a shelf for collection or wearing it :)

[@TheOriginalSinnerman]

Great mod idea. Kinda spendy though so personally I'd get a S**** clone bracelet and invert the display on the F91WG-9, if possible.

[@RedPixel2023]

Gold and black goes fine! Almost a dress watch for a fine cocktail party

[@3rdstone1]

Great work as usual, and another excellent mod. I have that F91W with the orange/gold trim at front. Now, this would lift that watch, esp. with getting the little detail with gold buttons. But needing a donator watch wouldn't work for me, only for that one mod. In your case I assume it's a different deal, as I guess you keep most leftovers for future mods. But that strap change alone made the basic F91W a little more fun. What model did that strap came from? Another question: Have you tried using parts/modded from those Skmei Casio replicas? If so, would their parts fit into real Casios?

[@Techsas]

Hey! Thanks! The strap is from A168WEGB-1B. I have not tried but I've heard that skmei parts fit on F91W.

[@3rdstone1]

@@Techsas Thanks for the info, and I'll check that model out.

[@Joshua-lw9lo]

Damn, that's really cool..

[@quietwave]

Fantastic work! What other model does F91W inverted LCD match? A168W is too expensive for me. lol

[@Techsas]

A158, A153 and others that use same size display

[@quietwave]

Thanks man! I'll look it up and maybe try the polarized sticker too

This is the only F-91W mod that should be allowed.

OMG BRO GOOD >!!!! HARD WORK! NICE ONE

[@Techsas]

Thanks!

[@cekpi7]

Shouldn't whole module from A168 fit in F91? Anyway, this is great since it isn't easy to remove polarizer, and glass shatters easily.

[@thenexthobby]

That's what I was wondering also.

[@Techsas]

A168 is much thicker both case and module. Thanks!

[@eastwood34]

What's the benefit of the F91 over the donor watch? Why not just use the other watch if it already has the inverted LCD? If it's purely looks, I can understand, that thing looks unreal!

I have the original F91-W with the gold trim, and of course this looks so much more awesome. Funny thing, watching the final result I instantly got reminded of one particular Formula One racing car team from the 70s: John Player Special. Those cars were in black with gold trim, and stuck out from the usual red, yellow, blue etc other racing cars. You should google JPS and easily see it. One actually could imagine the drivers back then wearing watches designed like this for promotion. Digital watches were all the rage back then.

[@Techsas]

Sorry, I just saw your comment now. I do agree with you, JPS cars looked awesome!
